Handsets losing registration on a regular basis

[cw1972]

Hi,

I have a remote site that has been working fine for some time, but recently I'm staring to see all the handsets at this particular site in the 'Registration Failed' state, a simple reboot is not allowing the registration to complete I am having to do a factory reset of the devices and reconfigure them, then they register immediately.

There are a total o 8 phones at this site, 2 x T26's and 6 x T19's.

There have been no changes in router / internet access / VPN to the PBX and I am yet to do any detailed network traces on the attempts that the handsets try when registering to see if I can see what is going on.

Just wondered if anyone had encountered behaviour like this before.

Any help would be much appreciated.

Thanks,

Christian

I now have the 3cdaemon syslog set up for when it next happens so I can gather information - I will also try sip debug information from within the asterisk cli and finally I have tcpdump /wireshark at the ready.

I think I have the tools at hand to try and pinpoint this - just need a better understanding of the information I will actually gather.
